Lithium carbonate, a lithium compound used in a range of industrial, is often the first chemical in the production chain for lithium products. Other compounds such as lithium hydroxide are usually produced with subsequent steps if needed, though some companies produce lithium hydroxide as the first step.
For this reason, investors will often see lithium production numbers broken down in terms of lithium carbonate equivalent. As with other lithium products, lithium carbonate may be produced from brines or from hard-rock deposits, although a few companies are also looking to develop clay-based lithium deposits.
